SSM框架整合Demo

目前项目大都开始采用SSM结构进行搭建，因为涉及项目比较多，新来的需求都是从现有项目中迁移一份出来进行修改，有的时候两个项目差别还是比较大，并不完全需要原有项目的东西，进行删减也是一项费神费时的事情，这里拉一个简单的demo，后续新的需求直接改用该项目。

具体如下几个步骤，搭建一个简单的基于maven的SSM Demo

1、创建maven项目

而后按照next下一步设置相关的目录等，搭建完的初始项目结构如下图所示：

2、增加java、resources等目录

增加test、java、resources目录，并设置成对应的资源文件，操作如下图：

3、修改pom文件，引入spring、mybatis等jar文件

这里根据以往项目的需求，引入了常用的jar，具体如下：

4、添加日志文件、jdbc、spring-mvc.xml及spring-mybatis.xml等文件

log4j.properties文件内容为：

#日志输出级别，控制台，debug文件，error文件
log4j.rootLogger = info,stdout,D,E  

#定义日志输出目的地为控制台
log4j.appender.stdout = org.apache.log4j.ConsoleAppender  
log4j.appender.stdout.Target = System.out  
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout  
log4j.appender.stdout.layout.ConversionPattern = [%c] - %m%n 

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender  
#指定输出目录  到tomcat/logs下
log4j.appender.D.File = ../logs/webtest-debug.log  
#定义文件最大大小
log4j.appender.D.MaxFileSize = 10MB  
log4j.appender.D.Append = true  
log4j.appender.D.Threshold = DEBUG   
log4j.appender.D.layout = org.apache.log4j.PatternLayout  
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH\:mm\:ss}  [ %t\:%r ] - [ %p ]  %m%n  

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender  
#指定输出目录  到tomcat/logs下
log4j.appender.E.File = ../logs/webtest-error.log  
#定义文件最大大小
log4j.appender.E.MaxFileSize = 10MB  
log4j.appender.E.Append = true  
log4j.appender.E.Threshold = ERROR   
log4j.appender.E.layout = org.apache.log4j.PatternLayout  
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n


log4j.logger.org.springframework=ERROR

#显示SQL语句部分

password-test=pass123

#定义初始连接数

#定义最大连接数
maxTotal=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间

5、根据需要添加controller、dao、mapper、service等文件，整合web.xml文件

web.xml文件内容为
